You know what gives the food it's flavor? The minerals.
Probably why salt enhances the flavor. Salt conducts an electrical charge.
Obviously, I'm not a trained scientist.
But I noticed when I poured some crushed supplements and minerals I'm taking
to try to keep this old machine working nicely over the prasadam the flavors of the foods were greatly increased.
Foods grown on depleted soils may look colorful,
especially after they inject them with coloring, but they don't have a wonderful taste.
Ever notice the difference between a store-bought tomato and a home grown tomato?
